Design, Analysis, and Verification of an Electro- Hydrostatic Actuator for Distributed Actuation System [PDF]
Sensors, 2020 In order to provide a simplified and low-cost solution of the terminal for a distributed actuation system, this paper proposes an electro-hydrostatic actuator (EHA) based on the linear drive principle. The proposed actuator is directly driven by a linear

Active Load-Sensitive Electro-Hydrostatic Actuator for More Electric Aircraft
Applied Sciences, 2020 In the flight control system, using an electro-hydrostatic actuator (EHA) instead of the currently used relatively mature electro-hydraulic valve-controlled actuator, there are three prevailing concerns, namely heating, size, and stiffness.
